I'm never a reviewer. I cant take this apart piece by piece. But i will try to make my recommendation as to how to watch this.
The story unfolds beautifully and kept my attention immediately.
You will see people that seem to genuinely interact with each other. you will see long pauses and long hesitations in the dialogue. It is stretched almost to a breaking point. you will hang on their every word.

Do not be afraid. Luckily the subtitles can keep up - very easily. If you are listening for their dialogue, you will not be able to hear it because of the poorly inserted music. I believe it is all in English and I know it is loud. The music drowns out the voices. I hated the monotonal singer Rachael Yamagata covers and really bad Bruce Willis singing Save the Last Dance For Me. If I never hear Stand By Your Man again, it will be too soon. This show ruined some songs for me.
After learning to turn down the music and letting the sound just quietly go on in the background, I read and watched this drama.
The style and wardrobe are minimal and drab. They practically sleep in their coats. And sleep in their clothes. It never improves until the absolute last scene.
The end two episodes were disappointing. I rewatched them hoping that i was missing something. I wasn't. But I would rewatch the drama again.
